Accenture Intern interview questions

I first did a resume drop after speaking to the recruiter on campus. I was invited for interview and it was 2 behavioral interviews but they seemed more like regular conversation interview. Before I left, I had to sign up for interview slots since the final interview round was in 2 days after the first. Then they contact me the next day saying that I have a case interview. There were 2 interview where one was behavioral and one was case. It took them a really long time for them to give me my offer.
